They are on the move! Who ? The Norfolk cuckoos that were fitted (last Spring) with solar powered 5G satellite tags. Through these devices, the cuckoos were followed back to their ‘winter homes’ in Africa. The tags transmit for about 10 hours at a time, then they go into 'sleep mode' whilst they are recharged by the light - ready to broadcast the position of the birds some time later ☆.

All of the cuckoos ended up in the same general area of the rain forest in the Congo. Some traversed the Sahara by flying directly over it it, whereas others took a more western route skirting the Sahara. Full details of their journey down to the Mediterranean and then into Africa can be see on the British Trust for Ornithology website here : http://goo.gl/EVxor
